Easy To Clean!By Guahan Reeferon 4/12/2015

Great Valve! Why worry about water filling your sump/refugium from water backfeeding through your return when you can install one of these valves? Side access cap makes cleaning quick and easy.

This valve is amazing. A bit pricey, but soo worth it. Just make sure you have quick disconnect fittings and a gate valve above just in case you need to clean it.

Worth the extra money!By Eric Ranschauon 2/13/2015

When I set up my 75 gallon tank the first time, I added a swing type check valve (http://www.bulkreefsupply.com/swing-check-valve-1-bcc097feafe80f489ef54b0720ca059c.html) to the return line. It lasted about eight months before it had gummed up sufficiently that it would no longer prevent back siphons when I turned off the return pump. Needless to say, they're very difficult to clean.

Replaced it last night with a Wye check valve and I couldn't be happier! It comes apart so I'll be able to clean it when it gets dirty, and I swear I'm getting twice the flow from my return line due to the more efficient design of the check valve itself.

Awesome check valveBy Eon 2/10/2015

This is the best check valve I have ever used. Much better than swing style valves. The build quality is solid - if you order one; you will understand the price when it is in your hands.

Only Check you should buyBy AJSon 11/25/2014

I have installed multiple versions of check valves, and this one is by far the best. I would suggest using unions for easy removal, and mounting in the proper manner to avoid and problems like I have read in other reviews.

Pretty Impressive so farBy AVon 9/27/2014

The quality of this product justifies the cost and I installed in my basin about a week ago. I'll have to inspect it in a month or two to stating that it's still functioning properly. Based on other reviews it is getting stuck in the open position after getting some debris or dirt in the check valve. One note, when it states 3/4 check valve, they are referring to the actual check valve itself, not the size pipe or hose you are connecting it to. That measurement OD is1", so I had to modify to allow it to work with my project.

Great valveBy Danielon 3/26/2014

There are tons of valves available, but the bottom line is if you can afford this one then buy it!!! If a piece of mind is what you are looking for this is the valve for you.

Have to keep it clean in order for it to work.By LTon 2/25/2014

I've had this about a year. Have to keep it clean in order for it to work. the piston valve gets stuck in the open position about 4 months after a cleaning.

I thought it was overpriced when ordering but was impressed to see how solid and well built it was. Works well and easy to maintain. Well worth the money for the peace of mind.

Failed to PerfomBy Christopheron 2/3/2014

Christopher wouldn't recommend this product to a friend

This check valve failed to perform during a power outage. I use it to stop the water from back-flowing from my display tank into my sump. The power went out one night and the check valve failed to close (this was within two weeks of purchase so it was still new/clean). This worked when I turned the power off to the pump, but failed in a real world power outage. I wish I could get my 50 dollars back, this was a complete waste of money and could have been a disaster if my sump wasn't big enough to contain all the back-flow.
